In addition to the basic components the KMG attachment includes a locating gage -- the "T" shaped item in the picture. The gage is used to center the attachment and aide in getting correct alignment to the router base.

Position the gage to the attachment base, slip the bolts through the corresponding holes. Note that this will center the 1/4" hole with the large bit hole in the base.

Chuck a standard 1/4" drill bit into the router.

Position the router motor back into the base Tighten the lock screw, place the attachment base using the centering hole as a guide.

Each router base will have an obvious optimum location for the attaching screws. This is a matter of rotating the attachment so the mounting holes can be drilled without interference.

Using a 3/16" bit drill the two mounting holes through the attachment and the router base.

Fasten the attachment to the router base with the screws and lock nuts that are provided

Attach the vertical guide to the attachment base using the bolts, washers, and nuts provided.

The desired depth of cut is a function of the bearing on the bit. The vertical guide is lined up with the selected bearing,

NOTE THAT THIS ATTACHMENT IS NOT DESIGNED OR INTENDED FOR USE WITH STRAIGHT NON-GUIDED BITS KMG DOES OFFER A STRAIGHT 1/4" BIT, ADJUSTABLE VERSION

Tighten the vertical guide nuts

The unit is now ready for some practice cuts go here for some operating suggestions. The tutor is for our "KMG IA binding attachment" but the principles are the same.

If you own or plan to purchase a bearing guided binding channel routing bit that looks like this:

Than there is no need to purchase one of these!

$400+ ??

$250+ ??

Millions of guitars have had binding and purfling channels routed using bearing guided bits and a device similar to this one ---

$45 + shipping

While the bearing guided bits are expensive there is no denying they produce a very uniform channel, that's 75% of the battle. The KMG attachment takes care of the rest, it is designed to allow the router to ride on the perimeter of the guitar regardless of contour and at the same time the vertical guide allows the operator to use the guitar side as the necessary natural path -- "just like" the much more expensive metal tools used in shops and factories around the world. This is what the novelty hobby gadgets pictured above are trying to accomplish in a very complicated manner.
